Good Morning! I recently worked on a small 40'' x 12'' diorama of the Carpenters Crossing at Strasburg. I developed a video to document my process. I'm pretty happy with the final product. Not including dry time for paint, glue, sculta-mold, or trees (which were already completed) this took me about 2 hours to build.
disclaimer (which I guess I need on any videos I post) - I'm not a professional film maker, I don't have expensive cameras and lighting. I film and post these videos to help other modelers that may be looking for a new technique for scenery.
